GOTTELAND S; GARAMBOIS Abstract Introduction 1 Grenoble Univertsity Maison des Géosciences L.I.RI.G.M. BP 53X 38041 Grenoble Cedex 9 France Common geotechnical in-situ tests are generally unable to characterise coarse heterogeneous soils (scree-slopes tills alluvial fans debris flows or slope deposits) once they contain pebbles or rocks with size larger than 100 to 150 mm. For such materials geophysical methods which are non-intrusive and able to investigate a large volume of soil allow the characterisation of coarse formations as
